Current - 2020

• Lead scientist in generative AI efforts in operations finance. Develop AI strategy and methodology for building and evaluating agentic systems. Mentor junior scientists on developing AI solutions.
• Employed statistical methods, mathematical decomposition techniques, and generative AI to automate analysis of outbound shipping costs, identify financial and operational deviations, and generate actionable insights directly leveraged for operational finance and financial planning. Created generative AI-driven analytical tools with interactive chat capabilities, enabling stakeholders to intuitively deep-dive into model results and financial reports.
• Led the development of machine learning and NLP models to proactively identify and mitigate fraudulent and abusive behaviors from third-party sellers, significantly enhancing the integrity of Amazon’s marketplace by preventing phishing, customer diversion, and related fraudulent activities.
• Designed and deployed forecasting models predicting demand for over 500,000 products globally, optimizing inventory management and customer satisfaction.
• Mentored and guided junior and mid-level scientists on statistical techniques, mathematical modeling, time series analysis, software engineering best practices, and career growth.
• Established monthly science reading groups and science office hours, fostering a collaborative environment and ensuring continuous engagement with the latest research and techniques.
• Managed end-to-end lifecycle of science solutions—from concept and model design through implementation and deployment on AWS cloud infrastructure (SageMaker, ECS, Lambda).
